Lab #36.2   Magnetism: Seeing Magnetic Fields

Purpose
In this activity, students will explore the patterns of magnetic fields around bar magnets in various configurations.

Discussion
A magnetic field is a kind of aura that surrounds magnets. Although it can’t be seen directly, the overall shape of the field can be seen by the effect it has on iron filings.

Required Equipment

3 bar magnets, iron filings and paper or a magnetic field protectoral (iron filings suspended in oil encased in an acrylic envelope)
